at first, his lies were clearly because they did not want me to lose respect for him, but the lying has progressed. essentially, the lie I do not want to confront him about concerns vacation plans. I asked this person to take a trip over Christmas as we are both living far from home and he lied a number of times about his plans. Instead of telling me he simply didn't want to travel with me (but still wanted to go abroad), he has lied and told me he is going home. I see this person on an almost daily basis. We email or talk to each other everyday. On a day to day basis, he is a great friend, but he doesn't seem to acknowledge that we are friends outside of a certain sphere. It makes me feel pretty used and I am not sure whether I should continue this friendship on a certain level (very shallow)...confront the person and let the cards fall where they may...or simply walk away from it entirely.
